Welcome to zolar! We’re on a mission to make solar power accessible to everyone and are proud to enable our customers to use the power of the sun in their own homes while making an active contribution to climate protection.

Get to know our team's tech stack choices better by having a look at our Zolar Tech Radar that lists our approach to languages and frameworks, platforms, processes and development tools we are looking to adopt or trial further.

  • Work closely with your team of developers, your product owner, QA engineer and your entire zolar development team.
  • Support your colleagues and be motivated to gain new knowledge and to share it within the team.
